The Philips HUE, everyone’s favorite color-changing lightbulb that no one can afford, is getting its own software developer program. With the addition, HUE owners are given a sanctioned way to vastly expand what their lightbulbs can do. And I bet the cogs of invention are already turning.

It’s all really neat stuff. Like the Nest thermostat, the Hue falls into that special class of electronics that takes something supremely domestic and makes it incomparably exciting. (Seriously — before the Nest, when was the last time you geeked out over a thermostat?)

The only problem, sadly, is price: Philips charges $200 for a three-bulb starter set and $60 for additional bulbs (and only at the Apple Store). As much as I love the idea of hackable lightbulbs, they’re not much use if I can’t afford to keep my lights on after I buy them.
